PRL's 11th-gen Civic 1.5T High Volume Intake uses a 4" oiled cone filter and a one-piece High Volume MAF housing to maximize airflow while keeping fuel trims accurate. The HDPE rotomolded airbox attaches to PRL's High Volume Inlet Air Duct and uses the factory air guide and seal for optimal airflow and heat-soak reduction, delivering a genuine 10 hp gain. Custom-molded 4-ply silicone with receiving grooves keeps every component securely attached without restricting flow, and the air filter stays accessible for maintenance without removing the airbox.

The optional Lower Duct takes this from a high-volume intake to a true cold air intake, drawing cooler air through the inner fender liner instead of engine bay air. That drops intake air temperature, increases airflow, and improves efficiency in low-pressure drafting zones — with the rotomolded HDPE construction still helping reduce heat-soak.
